Import Wordfence Settings from php code

Hello!

I can see the wordfence API documentation: https://www.wordfence.com/help/advanced/wordfence-api/

It has the function: wordfence::importSettings($token)

If I make a php script “test.php” server side like this:

<?php
require_once 'wordfenceConstants.php';
require_once 'wordfenceClass.php';

wordfence::importSettings('MY_SECRET_TOKEN')

?>

Then I get errors, any hints, tips or tricks? Thanks!:

php test.php
